I'm really interested in Elm, it's on my 'things to explore' list. But I've already built a big 'component' library for my designs and style in React, and it's hard to justify a switch to anything else for a long time.
And sadly that's the biggest problem the upcoming languages/frameworks face.
Nothing wrong with that. I'm on a greenfield project with no particular deadline, so I chose Rust + Elm, but if I had to build rapidly, or had already committed a bunch of code in another framework, I'd definitely stick with that.
Do you mix React and Knockout components by any chance? We are looking at moving from Knockout to React and I was wondering how painful this would be. My guess would be that if you are doing all or most of your KO stuff with components, then the switch shouldn't be too bad.
I've done some mixing of Knockout and React. We had a custom datagrid that was taking a long time to bind up all the data with templates. I think it was made almost 8x faster for rendering moving it to a React component. This was a POC project done probably 18 months ago.
